Above are samples of the styles of Weld Ring gaskets which are available from Klinger.

Two versions of this gasket exist, Welded Membrane gaskets as per style A21 and Weld Ring gaskets as per A22, A23 , A24 and A25.

Welded Membrane gaskets consist of two identical rings and the material must always be the same as the flanges, this ensures material compatibility

Weld Ring gaskets are also utilised in pairs and are manufactured from materials similar to that of the flanges, this ensures material compatibility. Used on difficult to seal heat exchanger or pipe flanges which are subject to extreme levels of cycling and temperature fluctuations.
